SCENARIO 11-7

Four brands of bubblegum were tested.A student chewed two pieces of a brand of gum and then blew a bubble,attempting to make it as big as possible.Another student measured the diameter of the bubble at its biggest point.The following table gives the diameters of the bubbles (in inches)for the 16 observations.
-Referring to Scenario 11-7,what is the critical value for testing the block effects at a 0.05 level of significance?
